Sorry to chime in so late, but I too am running the Levinson No 37/360S combo (feeding a No 32 Preamp). During my trial & error period, I tried the Transparent Reference AES/EBU as well as Better Cables Silver Serpent and a 1/2 dozen or so other cables I can't remember now. I reluctantly borrowed a Nordost Valhalla AES/EBU from my dealer and within a few minutes dialed him up to place an order. Not a cheap date, but the Valhalla removed several veiled layers, improved dynamics, tightened up the bass, dropped the noise floor a ton and improved things in nearly every aspect. That was about 10 years ago and I've never looked back.
